HvABI5 is involved in ABA-dependent drought response in barley

ABSTRACT: ABA INSENSITIVE 5 (ABI5) is a basic leucine zipper (bZIP) transcription factor which acts in the abscisic acid (ABA) signaling and is activated in response to abiotic stresses. It was shown that ABI5 binds ABA RESPONSIVE ELEMENTs (ABRE cis-elements) present in the promoters of regulated genes and activates or represses their transcription in response to stress. However, the precise role of barley (Hordeum vulgare) ABI5 in ABA signaling is still not well understood. We have identified a hvabi5.d mutant using barley TILLING (Targeted Induced Local Lesions IN Genomes) platform. hvabi5.d showed drought tolerant phenotype. To identify molecular mechanisms responsible for hvabi5.d response to drought, we perform drought-related gene expression analysis in barley in two genotypes: the wild-type (
